4. General Information

4.1. DESCRIPTION

The ASPIR pump has a compact construction, monoblock and vertical aspiration and impulse.

The ASPIR pump is made of a cold-formed stainless steel discharge casing, suction casing, diffuser and lantern

built by stainless steel investment casting, star-shaped fixed impeller and an external mechanical seal that

prevents any contact of the spring with the product.

The standard IEC motor of type IM B35 is protected by a stainless steel shroud and provided with height

adjustable hygienic designed legs in stainless steel too.

4.2. OPERATING PRINCIPLE

The impeller is housed between the suction casing and the diffuser and it rotates in conjunction with the pump

shaft. This arrangement, together with the rotation of the impeller and the arrangement of the side channel,

creates a negative pressure inside the suction casing, which generates the suction force of the pump. At the

same time, the fluid receives energy in the form of kinetic energy and pressure energy, and this impels it

through the discharge casing.

4.3. APPLICATION

ASPIR pump is a sanitary side-channel self-priming pump suitable for use in the food-processing,

pharmaceutical and chemical industries.

It is specially designed for pumping products containing air or gas, and it can also be used for negative suction

with prior priming as well as in filtration equipment. It can be used to pump wine, oil, syrups, volatile products

such as alcohol, acetone and other solvents or products at temperatures close to the boiling point.

However, the main use of this pump is for CIP return.

For each type of pump, the hydraulic performance is given by the choice of impeller diameters and speeds. The

characteristic curves also show the power and NPSH requirements. The intended use of the pump is defined by

its characteristic curve and operating limits provided in the 9. Technical Specifications.

The range of application for each type of pump is limited. The pump was selected for a given set of

pumping conditions when the order was placed. Misuse of the pump or its use beyond the

operating limits may be dangerous or cause permanent damage to the equipment. INOXPA shall

not be liable for any damage resulting from the incompleteness of the information provided by the

purchaser (nature of the fluid, rpm, etc.).

5.4.1. Excessive temperatures

Depending on the fluid to be pumped, high temperatures can be reached inside and around the pump.

Over 68ºC the operator should take protective measures and place warning notices advising of the

danger which exists if the pump is touched.

The type of protection selected should not isolate the pump entirely. It should allow for the bearings

to be cooled more efficiently and for the bearings to be lubricated.

5.5. PIPES

• As a general rule, install the suction and discharge lines in straight sections, with the minimum possible

number of elbows and fittings in order to reduce any pressure losses that may be caused by friction.

• Make sure that the pump’s ports are properly aligned with the pipework and have a diameter similar to that

of the pump connections.

• Place the pump as close as possible to the suction tank and whenever possible below the liquid level, or

even below the tank level in order to achieve the largest possible static head for suction.

• Install support brackets for the lines as close as possible to the pump’s suction and discharge ports in order

to avoid vibrations and stress on the pump.

5.5.1. Shut-off valves

The pump may be isolated for maintenance. To accomplish this, shut-off valves must be installed and

connected to the pump’s suction and discharge connections.

These valves must ALWAYS be open during operation of the pump.

5.6. MECHANICAL SEAL WITH QUENCH

Models with mechanical seal with quench may require the inlet and outlet connection to the cooling liquid.

See the limits of water consumption and pressure from the cooling circuit in chapter 9. Technical

Specifications.

5.7. ELECTRICAL INSTALLATION

Only qualified personnel can connect the electric motors.

Take the necessary measures to prevent damage to cables and connections.

Electrical equipment, terminals and components of the control systems may still carry current when

they are disconnected. Contacting them may impose a hazard to operators or cause irreparable

material damage.

Before handling the pump, make sure that the motor is stopped.

• Connect the motor in accordance with the instructions supplied by the motor manufacturer, in

accordance with the current national legislation and in compliance with EN 60204-1.

• Check the direction of rotation (see the signalling label on the pump).

• Start and stop the pump motor momentarily. Make sure that the direction of rotation is correct. If the

pump rotates in the wrong direction it could cause serious damage.

Before starting the pump, carefully read the instructions in chapter 5. Installation.

Carefully read chapter 9. Technical Specifications. INOXPA will not be liable for improper use of

the equipment.

NEVER touch the pump or the lines if hot liquids are being pumped.

6.1. CHECKS BEFORE STARTING THE PUMP

• Completely open the shut-off valves on the suction and discharge lines.

• If liquid does not flow towards the pump, fill it with the liquid to be pumped.

The pump must never turn dry.

• Check that the power supply matches the rating indicated on the motor plate.

• Check that the direction of rotation of motor is the right one.

• If the pump has the flow by-pass option, when it suction from a level below of the pump level, the by-

pass will be closed why it will not suction.

6.2. CHECKS WHEN STARTING THE PUMP

• Check that the pump is not making any strange noises.

• Check if the absolute inlet pressure is sufficient to prevent cavitation in the pump. See the curve to

determine the minimum pressure required above steam pressure (NPSHr).

• Control the discharge pressure.

• Check for leaks in the sealing areas.

Shut-off valves on the suction pipe must not be used to regulate the flow. All shut-off valves must

be fully open during operation.

Control the motor consumption to prevent an electrical overload.

Reduce the flow rate and the electrical power consumed by the motor:

• by regulating the pump’s discharge flow,

• by decreasing the motor speed,

• the pumps with an internal by-pass flow, open it (see performance curve with open/closed by-pass).

ATTENTION
